General Description
General Description The Alfa Laval Rotary Jet Mixer Iso-Mix 25 is a media driven and media lubricated tank/reactor mixer. As it is self lubricating, there are no lubricating substances such as oil, grease etc. in the machine, which need to be regularly changed.
Functionality The Alfa Laval Rotary Jet Mixer Iso-Mix 25 is placed inside the tank/reactor under the liquid surface of the liquid volume to be mixed. The mixer is combined with an external recirculation loop. The fluid of the tank/reactor is recirculated through this loop and reintroduced in the tank/reactor through the Alfa Laval Rotary Jet Mixer Iso-Mix 25. The more fluid being recirculated, the more effective mixing is obtained. The mixer should be placed in the centre of the fluid to be mixed. Minimum ½ meter under the liquid surface.

Possible liquid or powder supply
Possible gas supply
The flow of fluid to be mixed passes from the tank into the mixer through a turbine, which is set into rotation. The turbine rotation is through a gearbox transformed into a combined horizontal rotation of the mixer body and a vertical rotation of the nozzles.

General Description
Functioning (continued) The combined motion of the mixer body and the nozzles ensures a fully indexed tank mixing. After 11¼ revolutions of the Hub with nozzles (10 3/4 revolutions of the mixer body), one coarse movement pattern has been established which when projected on the tank surface looks as Figure 1. During the following rounds, this pattern is repeated 3 times, each of which is displaced ¼ of the mesh in the pattern. After a total of 45 revolutions of the Hub with nozzles (43 revolutions of the machine body), a complete “mixing pattern” has been laid out, and the first pattern is repeated. This feature eliminates "dead volumes" in the tank, and makes the Alfa Laval Rotary Jet Mixer Iso-Mix 25 a very efficient automatic tank cleaning machine, when the tank is empty.

2nd cycle
3rd cycle
4th cycle
The speed of rotation of the turbine depends on the flow rate through the mixer. The higher the flow rate is, the higher the speed of rotation will be. In order to control the RPM of the mixer for a wide range of flow rates, the efficiency of the turbine can be changed by using 50%, 100% or 0% turbine/inlet guide. Apart from this the machine can be supplied with a special slow turning gear; the E-gearing gear box Apart from the jet flow through the nozzles, fluid is leaking through the top of the mixer, at the hub and through the bottom cover. The leakages between the moving parts at the top and at the hub are cleaning the gabs and thus preventing build-up of material that might cause extra friction. The flow through the bottom cover is required to ensure proper lubrication of the gearbox. The time/number of rotations required for a satisfactory mixing of a given tank volume depends on the energy input (kw/m3 tank volume), the viscosity of the liquid, tank dimensions and number of mixers per tank. It is possible to add fluid, gas or solids in the recirculation loop. These ingredients will very effectively be mixed into the entire tank/reactor volume. When the tank/reactor is empty the Alfa Laval Rotary Jet Mixer Iso-Mix 25 can be used as a tank cleaning machine and the pattern shown above resembles the pattern of jets sweeping the vessel wall.

Installation and Normal Operation
Installation and Normal Operation General Safety and Installation Instructions The mixer should be installed in vertical position (upright or upside down). It is recommended to install a filter in the supply line in order to avoid large particles to clog inside the machine. Before connecting the machine into the system, all supply lines and valves should be flushed to remove foreign matter. It is recommended to secure the bolted connection between machine and down pipe against loosening to vibrations. Use Locking wire, nabs or equivalent for the actual application. ATEX Warning:
If the machine is used in potential explosive atmospheres, tapes or joint sealing compounds which are electrical insulators must not be used on threads or joints, unless an electrical connection is otherwise established to ensure an effective earthing. In addition, connecting pipe work, must be electrically conductive and earthed to the tank structure. The resistance between the nozzles and the tank structure should not exceed 20,000 Ohm. This is essential to avoid the build-up of static electricity on the machine. For further information see DS/CLC/TR 50404:2003 Safety of Machinery, guidance and recommendations for the avoidance of hazards due to static electricity.
Electrical equipment such as magnetic valves and electric actuators must not be installed in Ex-zones without type approval and marking, corresponding to the EX-class in question. Note: The machine shall be installed in accordance with national regulations for safety and other relevant regulations and standards. Precautions shall be made to prevent starting of the cleaning operation, while personnel are inside the tank or otherwise can be hit by jets from the nozzles. In EU-countries the complete system must fulfil the EU-Machine Directive and depending of application, the EU-Pressure Equipment Directive, the EU-ATEX Directive and other relevant Directives and shall be CEmarked before it is set into operation. The machine as delivered has been tested at the factory before shipping. For transportation reasons, the nozzles have been screwed off after the test. All you will have to do to make the machine ready for use is to refit the nozzles and tighten with wrench. Secure with Loctite No. 242 or equivalent. Check that the machine is in operating condition by inserting 3/16" hex Screwdriver (tool No. TE134A) in screw in top of Turbine shaft and easily turn Turbine shaft clockwise. If any resistance is recognized, the machine should be disassembled to localize the cause.
